ELECTROSURGICAL CUTTING INSTRUMENT - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240050149 titled 'ELECTROSURGICAL CUTTING INSTRUMENT

Simplified Explanation

The abstract describes an electrosurgical device that consists of a tubular outer shaft and an inner shaft. The outer shaft has a distal end region with a cutting edge and a window, while the inner shaft is coaxially maintained within the outer shaft and can move around the axis. The inner shaft is partially exposed in the window of the outer shaft. There is a first electrode on the outer shaft, proximal to the window, and a second electrode on the inner shaft, isolated from the first electrode and exposed in the window.

  • The device is an electrosurgical tool used for cutting and coagulating tissue during surgical procedures.
  • It consists of a tubular outer shaft and an inner shaft, allowing for precise movement and control.
  • The cutting edge and window on the outer shaft provide access for the inner shaft to interact with tissue.
  • The first electrode on the outer shaft and the second electrode on the inner shaft enable the application of electrical energy for cutting and coagulation.
  • The design allows for efficient and controlled tissue cutting and coagulation.

Potential Applications

  • Surgical procedures requiring precise tissue cutting and coagulation, such as laparoscopic surgeries or endoscopic procedures.
  • Minimally invasive surgeries where access and control are crucial.
  • Various medical specialties, including general surgery, gynecology, urology, and gastroenterology.

Problems Solved

  • Provides a more efficient and controlled method for tissue cutting and coagulation compared to traditional surgical tools.
  • Allows for precise and targeted application of electrical energy, reducing the risk of damage to surrounding tissue.
  • Facilitates minimally invasive procedures by providing a tool with improved maneuverability and access.

Benefits

  • Enhanced surgical precision and control, leading to improved patient outcomes.
  • Reduced risk of complications and damage to surrounding tissue.
  • Minimally invasive approach, resulting in smaller incisions, less scarring, and faster recovery for patients.
  • Versatility in various surgical specialties, expanding the range of procedures that can benefit from this technology.


Original Abstract Submitted

an electrosurgical device having a tubular outer shaft and an inner shaft is disclosed. the tubular outer shaft includes an axis and a distal end region. the distal end region includes a distal-most tip and a cutting edge defining a window in the outer shaft proximal along the axis to the distal-most tip. the inner shaft inner shaft coaxially maintained within the outer shaft such that the inner shaft is movable about the axis with respect to the outer shaft and wherein a portion of the inner shaft is exposed in the window of the outer shaft. a first electrode is disposed on the outer shaft in a region proximal along the axis to the window, and a second electrode is electrically isolated from the first electrode and disposed on the inner shaft. the second electrode is exposed in the window of the outer shaft.
